Usage

A new object will be created; the original object will not be modified.

Note: if a closed wire with sharp edges is used to create a spline, the new object may have self intersecting curve segments, and may not be visible in the 3D view. If this is the case, manually set DataMake Face to False to see the new shape, or set DataClosed to False to create an open shape.

Options

There are no options for this tool. Either it works with the selected object or not.

Scripting

There is no programming interface available for the WireToBSpline tool; however, creating a new object from the points of another is simple.

The Points attribute of an object is a list with the points that comprise that object; this list can be passed to functions that build geometry. Each point is defined by its FreeCAD.Vector, with units in millimeters.

Example:

importFreeCAD,Draft# Make a spline from the points of a wirep1=FreeCAD.Vector(1000,1000,0)p2=FreeCAD.Vector(2000,1000,0)p3=FreeCAD.Vector(2500,-1000,0)p4=FreeCAD.Vector(3500,-500,0)base_wire=Draft.makeWire([p1,p2,p3,p4])points1=base_wire.Pointsspline=Draft.makeBSpline(points1)# Make a wire from the points of a splinebase_spline=Draft.makeBSpline([-p1,-1.3*p2,-1.2*p3,-2.1*p4])points2=base_spline.PointsWire=Draft.makeWire(points2)
